Abstract: ZnO nanoparticles have been succesfully produced using Flame Assisted Spray
Pyrolysis (FASP) method. Burner type was a premixed flame reactor that used LPG as a fuel
and air as oxidizer because of an economical point of view. Zn(NO
was used as a precursor
source for ZnO nanoparticles production. The flow rates of carrier gas during ZnO nanoparticles
fabrication were 5 L/menit, 7 L/menit, and 9 L/menit. To get the information about size and
shape of ZnO nanoparticles was characterized using Scanning Electron Microscope (SEM) and
X-Ray Diffractometry (XRD). The results showed that the higher carrier gas flow rate, the bigger
size of ZnO nanoparticles. By using the flow rate of carrier gas at 5 L/min, the mean size of ZnO
nanoparticles was about 80 nm. ZnO nanoparticles at carrier gas of 5 L/min were hexagonal
zincite crystalline structure and XRD were about 30,62 nm
Keywords: Flame Assisted Spray Pyrolysis, nanoparticles, ZnO, LPG, SEM, XRD
